Abstract:This paper focuses on the design problem of a hybrid dynamical output feedback controller for exponential stabilization of a class of uncertain time-varying delay systems with actuator failures. By representing the time-delay system in the descriptor form and using the average dwell time technique, a new delay-dependent stabilization criterion for the existence of hybrid output feedback controllers is derived in terms of matrix inequalities. A cone complementary linearization algorithm is developed to design the hybrid output feedback controller. Finally, the effectiveness and the applicability of the proposed method are demonstrated by using two simulation examples. (C) 2009 Elsevier Ltd. All rights reserved.
